ADUM242E0BRIZ

Overview

The ADUM242E0BRIZ is a quad-channel digital isolator utilizing iCoupler magnetic coupling technology. It provides 5000 Vrms isolation voltage with a common-mode transient immunity of 75 kV/µs. The device supports data rates up to 150 Mb/s and operates on a single power supply ranging from 1.7 V to 5.5 V. Key electrical parameters include a propagation delay of 7.2 ns, rise/fall times of 2.5 ns, and a typical operating current of 11 mA. It functions in unidirectional mode within an SOIC-16 package across a temperature range of -40°C to +125°C.

Feature Summary

• Integrates four independent channels for bidirectional or unidirectional signal transmission using proprietary iCoupler technology.
• Provides robust high-voltage isolation capable of withstanding 5000 Vrms without external transformer windings.
• Delivers high-speed data transmission at rates up to 150 Mbps with low propagation delay and jitter.
• Features high common-mode transient immunity to maintain signal integrity in noisy environments.

Applications

• Industrial automation systems requiring galvanic isolation between control logic and sensors.
• Medical equipment interfaces needing certified isolation for patient safety.
• Power electronics gate drive circuits for monitoring and control signals.
• Data acquisition systems isolating analog-to-digital converter inputs from processing units.

Procurement Notes

Verify the specific suffix '0' against the official Analog Devices datasheet to confirm channel configuration and pinout compatibility. Ensure the SOIC-16 package dimensions match the target PCB footprint. Confirm RoHS compliance status through the manufacturer's latest documentation before finalizing procurement specifications.

Selection Notes

Select this component when four isolated channels are required within a compact surface-mount footprint. Compare performance metrics such as propagation delay and CMTI against alternative isolators if system timing constraints are critical. Verify that the 1.7 V to 5.5 V supply range aligns with the target logic levels on both sides of the isolation barrier.

Part Context

This part belongs to the ADuM242E series of quad-channel digital isolators. It shares the same core iCoupler architecture as other variants in the family but differs in specific channel configurations and packaging options. The series is designed to replace traditional optocouplers in applications demanding higher reliability and lower power consumption.

Replacement Considerations

Direct substitutes include ADUM242E1BRIZ for reel-packaged versions with identical electrical characteristics. Cross-reference pinouts carefully when considering generic quad-channel isolators from other manufacturers to ensure functional compatibility.
